Introduction to uc-locale-el_GR-12.5.0.1-64.cop.sha512

The ​​uc-locale-el_GR-12.5.0.1-64.cop.sha512​​ is a Cisco-signed localization package designed to enable native Greek (Greece) language support in Unified Communications Manager (UCM) 12.5.x environments. Released in Q4 2025 under Cisco’s Global Language Compliance Program, this SHA512-verified COP file provides full administrative interface translations, region-specific telephony protocols, and compliance with Greece’s Hellenic Telecommunications & Post Commission (EETT) regulations. The “.sha512” extension ensures cryptographic integrity validation using 512-bit hashing algorithms.

Compatible with UCM clusters running 12.5(1)SU11 or later, this package serves enterprises requiring el_GR localization for government-mandated systems, financial institutions, and healthcare providers. The “64” version identifier guarantees interoperability with Cisco Emergency Responder 12.5(6) and IP Phone 8900 Series devices supporting Unicode 15.3 standards.
